Abstract:The level of histone H4 mRNA was measured during spherulation and germination of Physarum polycephalum cultures. Histone H4 mRNA is present in prespherules as well as in mature and germinating spherules. During this differentiation process the cells have a 4C or G2-phase DNA content and therefore no DNA synthesis occurs. The presence of histone mRNA in the dormant cells shows that Physarum prepares long in advance for resumption of vegetative growth.
